摘要:

背景:骨关节炎是一种关节疾病,主要影响软骨,随着软骨细胞胞外基质的变化,软骨细胞发生凋亡,血管内皮生长因子在促进血管内皮细胞分裂与增殖、诱导血管生成中起重要作用。缺氧诱导因子是一种在细胞环境中的转录因子,因氧含量而产生不同反应,血管内皮生长因子和缺氧诱导因子在抑制软骨细胞凋亡中的作用受到研究者的重视。
目的:阐述血管内皮生长因子和缺氧诱导因子及其他可能因素对软骨细胞凋亡的影响。
方法:分析、总结近年来软骨细胞凋亡的影响因素的相关文献,从骨关节炎进程中软骨细胞血管内皮生长因子表达变化,血管内皮生长因子和缺氧诱导因子对软骨细胞凋亡的调控等方面进行阐述。
结果与结论:血管内皮生长因子通过上调抑制细胞凋亡因子的表达促进软骨细胞存活,缺氧诱导因子能增加软骨细胞活性和细胞外基质合成,成为抑制骨细胞凋亡的重要靶点,血管内皮生长因子与缺氧诱导因子的相关性还有待进一步研究。

Abstract:

BACKGROUND: Osteoarthritis is a joint disease that primarily affects the cartilage. With the changes of the extracellular matrix, chondrocytes appear to have apoptosis. Vascular endothelial growth factor plays an important role in promoting endothelial cell division and proliferation and inducing angiogenesis. Hypoxia-inducible factor is a cellular transcription factor and produces different reactions due to the oxygen content. Vascular endothelial growth factor and hypoxia-inducible factor are focused on inhibiting chondrocyte apoptosis.
OBJECTIVE: To elaborate the effects of vascular endothelial growth factor and hypoxia-inducible factors on chondrocyte apoptosis.
METHODS: Recent literatures related to chondrocyte apoptosis were summarized and analyzed. During the process of osteoarthritis, changes in vascular endothelial growth factors in chondrocytes and regulatory effects of vascular endothelial growth factor and hypoxia-inducible factor on chondrocyte apoptosis were elaborated.
RESULTS AND CONCLUSION: Vascular endothelial growth factor promote the survival of chondrocytes by upregulating the expression of anti-apoptotic factors, and hypoxia-inducible factor can increase the activity of chondrocytes and extracellular matrix synthesis, which has become an important target for inhibition of chondrocyte apoptosis. However, the correlation between vascular endothelial growth factor and hypoxia-inducible factor remains to be further studied.
